3 Java com.sun.star.lib.loader.Loader: Determines the location of an
soffice application, locates classes/juh.jar relative to the soffice
path, calls com.sun.star.comp.helper.UnoInfo.getJars there (which
returns the list of URE jar URLs), and loads the subordinate
application in a class loader that knows the URE jars. This no longer
works, as juh.jar is now located somewhere else.
Problem 3 could most silently be fixed by adding a fake
classes/juh.jar (containing only a modified
com.sun.star.comp.helper.UnoInfo.getJars that returns the correct list
of URE jar URLs) to each brand layer. The advantage is that an old
Loader continues to work against a new soffice installation. The
disadvantage is the somewhat dirty solution (have a classes subdir
only for the fake juh.jar, have a fake juh.jar with the same name as
the true juh.jar in the URE).

Just a question here:
in order to allow for using OOo 2.x from Java, I have a setup
routine that defines the classpath to point to
"OOoHome/program/classes/jurt.jar",
"OOoHome/program/classes/unoil.jar",
"OOoHome/program/classes/ridl.jar", and
"OOoHome/program/classes/juh.jar".
Would that setup still work for OOo 3.x? If not, what is the
recommended setup for classpath then?
No, that will no longer work. OOo is now split in three trees (URE,
Basis, Brand), and the necessary jars are spread across two of those
trees (jurt, ridl, juh in URE; unoil in Basis). If you are happy with a
manual setup (for which there are no guarantees of stability, of
course), see
<http://wiki.services.openoffice.org/wiki/ODF_Toolkit/Efforts/Three-Layer_OOo>
for details of how the lower (URE, Basis) layers can be located from the
Brand layer (which probably most closely corresponds to what you denote
OOoHome above). Or, better, try to use the "simple bootstrap"
mechanisms instead of a manual setup---we will try to keep those
mechanisms as stable as possible (though, as this thread shows, there
are situations when that stability cannot be absolute).
